一种自适应DCT域数字视频水印方案

摘要:

数字视频广播中的水印一般应当能够在视频编码的同时完成水印的嵌入。针对MPEG2视频压缩编码选用DCT变换进行数据压缩，提出一种自适应DCT域数字视频水印方案，数字水印主要嵌入在视频码流的I帧，嵌入强度和位置根据一定的准则自适应选取。实验结果显示，在不可感知性和鲁棒性方面，自适应方案具有良好性能。

A Solution to Self-adaptation DCT Digital Video Watermark

()

Abstract:

The watermark in Digital Video Broadcast(DVB) normally can be embedded simultaneously with the coding of the video.However,as in MPEG2 video compression coding,DCT converter is selected to make data compression,a solution to self-adaptation DCT digital video watermark is brought forward accordingly.With this solution,the watermark is embedded mainly in the I frame of video code stream,while the embedding strength and location can be selected under a self-adaptation strategy according to some certain rules.The lab experiment already shows that,the solution of self-adaptation has very good performance at non-apperceiveness and robustness.
